Whenever you are going to design Custom Packaging, your packaging supplier must ask for the box dimensions to create an exclusive personalized wrapping solution for your product. That’s why it is important to know how to measure the dimensions of a box, perfectly.

What is a Dimension?

A dimension refers to a measurable extent of some kind, such as length, width, height, depth, or size. In various contexts, it may mean different things. But in our everyday context when we talk about the dimension of a box it means that we are talking about the length, weight, and height of a box.

What Are the Dimensions of a Box?

When it comes to packaging and shipping, it is crucial to learn about the perfect box dimensions. The right box size ensures the suppliers secure delivery of the packed items. The selection of the perfect box minimizes the risk of product damage and also helps in optimizing the shipping cost.

Understanding different factors of Box Dimensions

Whenever someone talks about the box measurements three important quantities should be measured. And these three are the length width height of a box. Although there is a specific order of these quantities, that should be considered generally.

However, the order of box dimensions is typically listed in the order of Length (L) x Width (W) x Height (H). So if anyone provides a 2x3x4-inch box measurement. Then it means that

2 inches is the length of the box.

3 inches is the Width of the box and

4 inches is the Height of the box.

So the Box dimension order is Length x Width x Depth (L x W x D) or Length x Width x Height (L x W x H).

Breaking Down the Box Dimensions

Here’s a quick breakdown of what each term means:

  1. Length (L)

This is the box’s longest side. The box has the longer of the two dimensions when seen from above.

  1. Width (W)

When looking at the box from the top, this is its shorter side.

  1. Height (H) / Depth (D)

This is the side that is vertical to the length and Width; it is the height or depth of the box.

However, the term height width, and length of the Box can vary according to the box shape and style. For measuring the dimensions of Box which is designed in the display box style has two different depths. One for the head side and the second for the front side.

Similarly, a mailer box has a different dominant dimension which is the length of the box. In the same way, a longer box has more depth which becomes its prominent dimension. You can easily analyze from the given dimensions what is the length width and height of a box.

Calculate the Volume of a Box

Calculate the Volume of a Box

After understanding the length width and height of a box now you can easily calculate the volume of a box. The calculated volume can help you decide which product can fit properly inside the box.

You can easily calculate the Volume of your custom packaging box with a simple formula.

Height x Width x Length = Volume

Simply multiply all three dimensions i.e. box length width height and get the volume of your customized packaging box. However, it is very simple and easy to calculate the volume of a box.

But if you find mathematics a bit difficult you can use any online volume calculator that can help you calculate volume by just entering box dimensions length width height.

How to Measure Box Dimensions?

There are three steps how to measure the length width height of a box that may lead you in calculating the dimensions of a box.

  1. Measure the length
  2. Measure the width
  3. Measure the height

Place the measuring tape along with the long side of the box. Now view from the top and measure the shorter side that is the width of the box. For height, measure from the base to the top of the box.

However, keep this in mind always measure from the inner side of the box. Because the inner dimensions are crucial for the perfect packaging and also play a vital role in the secure shipment of the product boxes.

Every box has its unique measurements and values. Cereal Box dimensions can never be the same as the dimensions of the custom shoe box.

External Vs Internal Dimensions of Boxes
